// There are at least seven different ways in a which a file can be saved or downloaded. This
// test ensures that the filename is determined correctly when saving in these ways. The seven
// ways are:
// - save the file individually from the File menu
// - save as complete web page (this uses a different codepath than the previous one)
// - dragging an image to the local file system
// - copy an image and paste it as a file to the local file system (windows only)
// - open a link with content-disposition set to attachment
// - open a link with the download attribute
// - save a link or image from the context menu
